Conteúdo: | Field trials were conducted at Ballantrae (soil pH 5.0) to assess the value of Chatham Rise phosphorite compared with superphosphate to increase DM production of hill pastures. 105 kg P/ha as superphosphate applied in 3 equal parts over 3 yr increased DM yield from 3.98 t (control + S) to 4.93 t/ha in the 1st yr, and from 4.67 to 7.26 t/ha in the 3rd yr. 70 kg P/ha applied in the 1st yr as Chatham Rise phosphate increased DM yield to 4.98 t in the 1st yr and to 7.14 t/ha in the 3rd yr.
